I'm 99% sure Mike (Bulldog) has a 8.8 straight (Tube) axle rear end. It's funny last time we were under mine, Rob (Snake Charmer) said the rear end is the weak link, then we found the tab, that's say's it's a SVO 3.55 LSD, good for around 500HP, so it's still the tires that are the weak link
If you spin the rear tires (Off the ground) Mike, do both spin in the same direction ? If so you have a LSD. Hopefully you have the same one I have. If you need a pic. I will get you one or two. Cheers Tom.
